Abstract :
Median filters are very important nonlinear filters, finding many applications in image and speech processing. In recent years analogue implementation of nonlinear filters has gained new interest. In this work, a novel current-mode analogue median filter is proposed. The design employs a combination of current absolute value circuits with a current minimum circuit and a majority gate
